Salpiglossis, or painted tongue, offers up a kaleidoscope of color, with each flower rich in shadings of pigment and strong veins. Related to petunias, salpiglossis have the same open-faced, trumpet-like flowers. Natives of Chile, they're well worth extra effort to grow.

Unlike petunias, salpiglossis is a relatively upright grower, reaching up to 90 cm in the garden. Flowers are about 6 cm in diameter. The colors are cream, lemon-yellow, gold, orange, brown, red, scarlet, violet, and near blue. Most of them are overlaid with veins and other patterns of color, making them look like stained glass.
